MAIN COMPONENTS AND FUNCTIONS DESCRIPTION

Parts name Functional description
WCM Controls the keyless entry functions, TPMS functions and starting of the engine by using the following communications.
  • Communications with ETACS-ECU, ECM, ASC-ECU and combination meter via CAN
  • Wireless communication with the ignition key (transponder)
  • Wireless communication with the ignition key (transmitter) via the receiver antenna assembly
Receiver antenna assembly Receives the operation signals from the lock/unlock buttons, trunk lid button, and panic button on the ignition key (transmitter) as well as the tire pressure signal from the TPMS transmitter. Then, transmits them to WCM.
Ignition key The ignition key also sends signals to receiver antenna assembly when the lock/unlock/trunk lid button and the panic button on it are operated.
Combination meter (Multi information display, TPMS warning light) Communicates with WCM via CAN. Send ignition switch status. Receives the warning request or warning information about TPMS from WCM, activates(1) the TPMS warning light. Warning symbol and message is additionally displayed on the multi information display.
ETACS-ECU Communicates with WCM via CAN. By the door lock/unlock request, trunk lid open request, or panic alarm request from WCM, ETACS-ECU outputs the lock/unlock signal, trunk lid open signal, or panic alarm signal. When the door lock/unlock signal is output, ETACS-ECU flashes or illuminates the turn signal light and dome light to notify that the lock/unlock operation is performed.
ASC-ECU Communicates with WCM via CAN. Sends the vehicle speed data.
ECM Communication with WCM via CAN. Send atmospheric pressure data.
TPMS transmitter Measure tire pressure directly, then send radio frequency signal to receiver antenna assembly.
NOTE:
  • (1) Illuminates for tire pressure warning.
  • Flashes for about 1 minute and then continuously illuminated for TPMS malfunction warning.
